What can I say about Vamos? My boyfriend and I took 12 weeks of classes here in early 2013. Our goal was simple: we wanted to learn Spanish living in South America. After 3 months of 20-hours a week group classes we are now very confident in our ability to read, write, speak and, for the most part, understand (Argentines have a very peculiar accent!).
The best part about Vamos, from a student point of view, is the teaching staff. Most of the teachers are University of Buenos Aires students. All of them are very bright, many study linguistics and literature, and every one is good at, well, teaching. I had 4 teachers in my 12 weeks and each one was excellent. For a few weeks I was the only student at my level so they put me into one-on-one lessons with an instructor; the teachers are great at teaching both group and private lessons. With all my time there I met more than a few students who tried out other schools and were disappointed with the teachers. Every last one of them was thrilled with the teachers here, as I was.
From an academic point of view, the material is exceptionally helpful and conducive to learning. Vamos does not use a textbook; you get a looseleaf sheet for every topic. The material is assembled by the academic director who makes a specific lesson plan each week for each group. Do people in the class have issues with pronouns? imperfect vs. indicative? The teacher will focus on that topic for you, with supporting material. At a more advanced level I asked to go over the various uses of "se" in Spanish, a tricky topic. The academic director put together a lesson plan and we spent a whole day on it. Also, though I took classes in the busy summer months I never had a class with more than 4 students in it.
Last, but certainly not least, the staff is incredibly helpful and friendly. Kat and Ingrid were life savers in many occasions, answering all the necessary beginners questions when living in a new city. They also organize weekly movies and workshops, like how to drink mate, how to spot fake money, and how to use the bus sytem, which were invaluable and interesting! Not only that, they alert you to cultural events. They informed us of a international polo match going on, which several of us went to (for the first time) and had a blast!
If you're going to study Spanish in Bs As, study at Vamos. Not a single person I met who studied at Vamos and was interested in seriously learning Spanish was dissatisfied. If I wasn't moving on to another country I would still be there taking classes. It was the highlight of my 4-month experience in Argentina.
